The daily life of the substitute messenger

Story of: The daily life of the substitute messenger

Gaining the power of a substitute through time travel, I thought it would be the beginning of a passionate youth comic. Why is the world so peaceful?

Why am I living a stable life as a high school student when I'm afraid of all my four eggs?

Yukinoshita, don’t think that I really won’t hit you!

Kasumigaoka, can you stop trying to make me the hero of your novel?

Sigong, I won’t confess to you, give up!

Woo hoo, it’s better to be Xiao Hui, please comfort me~
